VALVE-COUPLING.

Application filed. .Tune 28,

To all afirma t may concern:

Be it known that 1 ,Ron1i1rr JiiMns Nonins, a subject oi the King ofGreat Britain, and resident oit the city of Montreal, llrovince ci?Quebec, Dominion of Canada, have invented certain new and usefulimprovements in Valve-Couplingsg and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

lleretoiiore in connecting a pair of branch lines to a single pipe linea plain coupling has been controlled by a valve entirely separate fromthe coupling. This arrangement oi` parts not only required an extravalve iitting and the necessary threading of the pipe ends but added tothe possibility of breakage.

rlhe object of my invention is to provide a tivo line valve whichcombines in one integ-ral member both coupling and valve and whichconsequently overcomes the disadvantages referred to above.

To this end my invention consists of a two line valve having a couplinghead in the axial plane or' the valve proper for connection to theintake line and a pair oi' integral offset coupling heads for connectionto the branch lines.

For full comprehension of my invention reference must be had to theaccompanying drawings in which similar reference characters indicate thesame parts, and wherein:

Figure l is a side elevation oi myimproved two Way valve;

Fig. 2 is a plan view illustrating the branch coupling heads;

Fig. is a longitudinal. sectional view taken on line 3 3 Fig. 2;

Fig. l is a transverse sectional view taken on line P-l Fig. l; and

Fig. 5 is a detail elevation oi' the valve proper.

The body or casing oi the valve consists oi an integral casting 2 havingan inlet 3 and branch outletsfland o oiiset from the axial line of theinlet port. The valve proper which is oi? substantially conical i`3or1nis indicated at 6 and its axial plane coin cides with the plane of theintake pipe line, the casing being internally screw-threaded as at 8 toreceive the latter. The valve case presents a chamber 9 of conical formto rotatably receive the valve proper and the smaller end oi suchchamber has an opening Specieation of Letters Patent.

sufficient to permit the squared end l0 of the valve proper to projecttherethrough. n lever l2 for openingand closing the valve is rigidlykeyed to this squared end.

The branch outlets l and 5 extend at right angles to each other andcontain passages l5 and 16 respectively, the latter terminating inoblong ports 17 and 18 opening into the valve chamber, the length oi theports being parallel to the axial plane of the valve. Ports 11,9 and 2Oin the valve proper are adapted to register with the rst mentioned portsand ei'lect `communication between the passages and the valve chamber 2lWithin the valve proper.

A universal coupling head 25 is formed integrally with each of theoutlets t and 5. This head is of relatively large diameter to provide achamber 26 sufficiently large to contain, While maintaining a clearpassage for the air or steam, a pair of diametrically oppositelypositionedlugs 27 and 28 and teats 29 and 3() located diametricallyopposite each other and in a plane at right angles to the plane of thelugs. The lugs and teats are formed inegrally With the inner Wall 38 ofthe head. This coupling head is adapted to be connected to a head ofidentically the same construction as indicated in Fig. the lugs on onehead engaging the teats on the other and vice versa. In order that thelugs may become moved into locking engagement With the teats by a slightturn a socket 3T is formed in the outer iace of each lug and is extendedlaterally to constitute an opening 31 permitting the entry of the teatthereinto, and the inclined surface 32 causes the coupling heads to comeinto tight contact when connected. A circumferential groove 35 is formedin each head and contains an annular gasket 36 which projects out of thegroove and the gaskets of each pair oi coupled heads being in tightcontact. The joint is tightened When the internal pressure increases asthe gaskets are caused to expand. i

In order that the branch lines may be relieved oi pressure when thevalve is closed, the valve proper has a blow-ofi1 passage 40 thereinextending from the squared end o'l the former to a point at Which itWill effect communication successively With the passages 15 and 1G asthe valve is turned from open to closed positions.

What I claim is as follows:

1. A valve coupling for connecting an intake pipe line and a pair ofbranch lines; said coupling consisting of a unitary integral castingincluding a pair of offset outlets for connection to the branch lines, avalve Within the casting and located on the axial line of the intakepipe line and controlling the outlets, and a blow-off passage in saidvalve adapted to successively relieve the branch lines of pressure whenthe valve is moved from open to closed positions.

2. A valve coupling for connecting a single pipe line to. a plurality oflines extending parallel to said single line, said coupling consistingof a casting having a conical valve chamber, the opposite ends of saidchamber being open, the larger end communicating with said single pipeline, a plurality of passages radiating from said chamber, each of saidpassages being offset to locate its outer end in alinement with one ofsaid plurality of lines, and a conical valve rotatably tting within saidchamber for controlling said passages and having its smaller endprojecting through and closing the smaller end of lthe chamber, saidprojecting end enabling the valve to be turned.

3. A valve coupling for connecting a single pipe line to a plurality oflines extending parallel to said single line, said coupling consistingofV a casting having a 'conical valve i with the length of thel oblongextending substantially parallel to the axis of the valve chamber and ahollow conical valve rotatably fitting within said chamber forcontrolling said passages, said valve having a plurality oflongitudinally dis osed oblong openings therein adapted to e ectcommunlcation between the passages and said valve chamber, the smallerend of the valve projecting through and closing the smaller end of thechamber, said projecting end enabling the valve to be turned.

4. A valve coupling for connecting a single pipe line to a plurality oflines extending parallel to said single line, said coupling consistingof a casting having a conical valve chamber, the opposite ends of saidchamber being open, the larger end communicating with said single pipeline, a plurality of passages radiating from said chamber, each of saidpassages being offset `to locate its outer end in alinement with one ofsaid plurality of lines, said outer end being of substantially circularcross section and the inner end being of substantially oblong crosssection with the length of the oblong extending substantially parallelto the axis of the valve chamber, and a hollow conical valve rotatablyfitting within said chamber for controlling said passages, said valvehaving a plurality of longitudinally disposed oblong openings thereinadapted to effect communication between the passages and said valvechamber, the smaller end of the valve projecting through and closing thesmaller end of the chamber, said projecting end enabling the valve to beturned, and a blow-off passage in said "alve adapted to successivelyrelieve said plurality of lines of pressure when the valve 1s moved fromopen to closed position.

In testimony whereof I have signed my name to this specification in thepresence of two witnesses.
